Discussion • AP m4a Files Now Not Accepted by Apple Music

MY QUESTION: HOW DO I GET M4A FILES FROM AP TO WORK WITH APPLE MUSIC?

Something has changed somewhere.

Recordings saved as m4a files from AP 2.8.13 on an M1 Mac Mini running Ventura 13.6.1 aren’t recognized by Apple Music 1.3.6.14.
This never used to be an issue.

If I make a recording using AP and do Save As or a Split According to Markers and specify m4a as the format, the resulting files are ignored by Music.

After many hours of troubleshooting and testing, here’s what I know:

1. An m4a file created with AP in June of this year works fine with Music. Invisor reports the format of this file as ALAC.

2. An m4a file created today with AP does NOT work with Music. Invisor reports the format of this file as fpcm.
The same fpcm file opens and plays normally in QuickTime Player without a problem.
If I export the file from QTP to a new m4a file, Invisor now reports the format as AAC LC, and it DOES work with Music.
Files saved from AP as mp4 or aif work fine with Music. Only m4a files have a problem.

What is going on?
